You can make your sheet / title block in word, powerpoint, or the equivalents, then either import your pictures directly onto the sheet (you’d have to be careful with scale) or do it on a pdf and same. I spent some time trying to work out how to get accurate scaled SU-Make drawings onto a word document, and then I did a price / time comparison and decided it was easier to just buy SU-pro. 
Of course, I was also comparing prices to revit… and I gotta say, for the ease / range of use vs price, it really wasn’t a question at all. 
Of course, OP, you’re missing the opportunity to import your friends’ SU files and put them into LO and charge them a small amount to do their documentation. Lol.
Some excellent workarounds here.
